Product Advantage
High strength steel wire rope clamps/hot-dip galvanized anti-corrosion rope clamps/heavy-duty lifting safety accessories are forged from 45 # high-quality carbon steel, quenched and tempered, with a tensile strength of over 800MPa, which is 30% higher than ordinary carbon steel materials. After professional testing, it can withstand over 50000 vibrations without looseness under rated load, ensuring long-term safe and reliable use.
Anti slip steel wire rope clamp/self tightening safety rope clamp/anti loosening lifting accessories cover multiple models of M4-M48, suitable for 6mm-60mm diameter steel wire ropes, meeting the needs of lifting, traction, high-altitude operations and other scenarios. Special specifications support customization, adapting to the fixing requirements of steel wire ropes in different industries
Low temperature resistant lifting accessories/marine engineering special rope clamp U-bolts are tightly matched with saddles, and the surface is treated with serrated patterns, increasing friction by 40%. The steel wire rope is firmly clamped without slipping. After testing, the clamping force can reach 80% of the breaking force of the steel wire rope after correct installation, far exceeding the industry standard.
The surface is treated with hot-dip galvanizing, with a zinc layer thickness of ≥ 85 μ m, and there is no rust after more than 1000 hours of salt spray testing. In harsh environments such as humidity, acidity, and alkalinity, the service life of coatings is extended by more than twice compared to ordinary coatings, reducing maintenance costs.

Product Applications
Wire rope clamps are widely used for fixing the ends of wire ropes in equipment such as tower cranes, elevators, and scaffolding. Its high strength and wear resistance ensure the safety of heavy lifting, especially in frequent dynamic load scenarios. During installation, it is necessary to arrange according to standard spacing and regularly check the tightening status of bolts.
Stainless steel wire rope clamps can resist seawater corrosion in dock mooring, ship cranes, and offshore platforms. The double clip (W-shaped) design can enhance tensile strength and is suitable for high load operations in extreme weather conditions, such as anchor chain fixation or towing operations.
Mining hoists, conveyor belts, and cableway cables rely on steel wire rope clamps to connect key stress nodes. Carbon steel galvanized clamps are impact resistant and rust resistant, suitable for dust and humid environments. Choose a model that matches the rope diameter and avoid deformation of the clamp caused by overload.
Used for fixing cables in high-voltage power towers and signal towers to ensure structural wind resistance stability. The fixture treated with hot-dip galvanizing can resist outdoor ultraviolet rays and rainwater erosion for a long time. When installing, attention should be paid to the direction of the rope clamp to balance the force.
In tractor towing ropes and logging lifting equipment, wire rope clamps provide a fast and reliable connection solution. Lightweight design facilitates field operation, but requires regular lubrication of bolts to prevent rusting and jamming.
In scenarios such as rescue ropes and military floating bridge construction, high-strength alloy steel wire rope clamps can withstand sudden impact loads. Stainless steel material is suitable for harsh environments and meets the requirements for quick disassembly and assembly.
1. Check products and tools
Verify the model: Ensure that the wire rope clamp matches the diameter of the wire rope (with an error of ± 1mm).
Preparation tools: torque wrench, lubricant (optional), gloves, and safety gear.
2. Determine the installation location
Active end and dead end: The clamp must be pressed against the "active end" (force side) of the wire rope, with the bolt facing the "dead end" (fixed side).
Spacing requirement: The spacing between adjacent rope clamps should be 6-7 times the diameter of the steel wire rope (such as 60-70mm for a 10mm diameter rope).
3. Install the rope clamp
Preliminary fixation: Clamp the rope clamp onto the steel wire rope and manually tighten the nut to a slight force.
Symmetrical arrangement: Use at least 3 rope clamps (rope diameter ≤ 19mm), evenly distributed and maintain consistent direction.
4. Tighten the bolts
Torque calibration: Operate according to the standard tightening torque (such as 15-20N · m for M8 bolts).
Secondary inspection: After tightening, gently tap the clamp seat to confirm that there is no looseness or offset.
5. Load testing and maintenance
Empty load test: Gently pull the steel wire rope and observe whether the rope clamp slides.
Regular maintenance: Check the tightness of bolts and the wear of the clamp seat every month. If there is severe corrosion, it needs to be replaced
FAQ
Definition: A wire rope clamp is a metal fixture used to secure the end of a wire rope, connect or lock the wire rope, typically consisting of a clamp seat, U-bolt, nut and other components.
Main function:
Secure the end of the steel wire rope to prevent it from loosening or slipping (such as in lifting, towing, or bundling scenarios).
Classified by structure
U-Bolt Clips: The most common type is a combination of U-bolts and clamps, suitable for general fixation.
Double Saddle Clips: Both sides are flat plates, reducing damage to the steel wire rope and suitable for high-strength applications.
Drop Forged Rope Clamp: Forged into shape, with higher strength, used for heavy lifting (such as ships and mines).
Classified by Material
Carbon steel rope clamp: universal, economical and durable.
Stainless steel rope clamp: corrosion-resistant, suitable for marine, chemical and other environments.
Matching the diameter of the steel wire rope: The rope clamp model should strictly correspond to the diameter of the steel wire rope (such as a 10mm steel wire rope with a 10mm rope clamp).
Workload (WLL): It must meet safety requirements and overloading is strictly prohibited.
Usage environment: Stainless steel material is preferred for humid/corrosive environments.
Place the live end (short end) of the steel wire rope close to the U-bolt side. Tighten the nut to the specified torque (usually 1/3 to 1/2 of the diameter of the steel wire rope). Check for clamping after installation to ensure no sliding.
